In elastic: General Purpose Interface to 'Elasticsearch'

Description

Mapping management

Usage

mapping_create(
  conn,
  index,
  body,
  type = NULL,
  update_all_types = FALSE,
  include_type_name = NULL,
  ...
)

mapping_get(conn, index = NULL, type = NULL, include_type_name = NULL, ...)

field_mapping_get(
  conn,
  index = NULL,
  type = NULL,
  field,
  include_defaults = FALSE,
  include_type_name = NULL,
  ...
)

type_exists(conn, index, type, ...)

Arguments

conn	an Elasticsearch connection object, see connect()
index	(character) An index
body	(list) Either a list or json, representing the query.
type	(character) A document type
update_all_types	(logical) update all types. default: FALSE. This parameter is deprecated in ES v6.3.0 and higher, see https://github.com/elastic/elasticsearch/pull/28284
include_type_name	(logical) If set to TRUE, you can include a type name, if not an error will occur. default: not set. See Details.
...	Curl options passed on to crul::verb-PUT, crul::verb-GET, or crul::verb-HEAD
field	(character) One or more field names
include_defaults	(logical) Whether to return default values
